In this sought-after guide, discover why these OEM parts outshine copies, how they’re engineered for the Mercedes AMG G-63, and why they safeguard resale, performance, reliability, and your sense of Showroom pride.
Why OEM Parts Matter for the G-63
Every Mercedes G-63 owner values authenticity and wants the ultimate combination of performance and luxury.
Moreover, Original Equipment Manufacturer (OEM) parts like the Mercedes AMG G-63 Exhaust System LH & RH Silver and Black OEM A4634901504 and the Mercedes AMG G-63 Hood Black Matte OEM A4638802700 deliver precision fitment and original design provenance straight from Mercedes’ factory.

Consequently, resale value hinges on a documented history of dealership-certified OEM upgrades and replacements.
Similarly, choosing genuine parts ensures critical safety and reliability standards, which is non-negotiable for a 577-hp legend like the G-63.

OEM vs Aftermarket: Why Original Wins
When shopping for parts like the Mercedes AMG G-63 Hood Black Matte OEM A4638802700 or the exhaust system, it’s tempting to consider aftermarket or replica alternatives.
However, aftermarket body panels often lack the factory’s aluminum or steel alloys, leading to poor fit, rattles, and mismatched finishes.
In contrast, original Mercedes AMG G-63 panels and exhausts always line up perfectly, use patented coatings, and match the car’s weight and rigidity specs—key to preserving limited-warranty coverages and ISO safety standards.
Furthermore, OEM packaging includes all required mounting and adjustment hardware, so you never run into mismatched fasteners or parts shortages midway through the job.
Meanwhile, for performance applications like the exhaust, only Mercedes supplies the full suite of engineered actuators, baffles, and sensor housing provisions.
As a result, you guarantee that every drive sounds, feels, and performs like it should—as engineered in Affalterbach.

Installation Tips and Maintenance Best Practices
Proper installation and care ensure your G-63 parts last and maintain that new-car thrill.
Meanwhile, certified technicians or advanced DIYers can use the supplied OEM guides for direct replacement, ensuring correct torque specs and electronic adaptation—especially for items like the active exhaust or power-dome hood.
Moreover, always inspect components for shipping damage before unboxing.
Genuine mounting kits come with all gaskets, heat shields, and electronic connectors.
Similarly, regular checks of hangers, bushings, and electro-actuators keep the exhaust system in peak form and ready for performance driving.
In addition, cleaning shows off that sought-after matte or ceramic finish while preventing corrosion or pitting.
Thus, always use Mercedes-approved cleansers, and avoid abrasive compounds on Black Matte finishes or exhaust tips.
Consequently, your G-63 always shines and performs with Showroom precision.
